I\'ve started off by taking a look at your figures. You\'re off to a good start, no sloppiness evident, you can stay within the lines well. So far though, the minis I have looked at have zero shading or highlighting. Or at least they look that way, if you did shade and highlight, you\'re not using enough contrast. Your minis are also a tad glossy (more of a satin than gloss really), and this tends to put off some people. Finally, while I understand not wanting to finish your bases if you\'re just gaming with the minis, this will really hurt your score.
Suggestions:
1. Start with simple shading and highlighting, namely washes and drybrushing. For example, on your winged demon with the dark blue wings, you could keep the wings dark blue, but wash with a blue/black mix of thinned paint. After that dries, you could drybrush (use a brush you don\'t care about - drybrushing kills brushes) with first the base color (to drybrush, load your brush with paint, then remove most of the paint by running the brush over a paper towel, left behind is a small amount of paint on the brush which you run lightly over the wings. The uppermost parts will pick up the paint, leaving the depths darker). Drybrush again - but try to do so lighter so you don\'t cover up the color from the step before - with perhaps a mix of the dark blue and a medium blue, or even just a medium blue. Also remember that for minis of this size, you have to artificially add contrast to make them look good. This is something I still have problems with, I shade and highlight, but sometimes not enough...
2. Use a matte sealer to seal your minis (I find both GW\'s Matte Sealer and Testor\'s Dullcoat to be good). Shake the can well before use. Test it out first on a piece of cardboard to make sure it won\'t go white on you. Shake some more. Spray your mini(s) to be sealed LIGHTLY, if you overspray, the mini will tend to go glossy. It\'s better to do several lighter layers than one thick one.
3. Basing can be done very quickly and easily to at least an adequate level (enough to raise you up to a 6 anyways - I tend to score in that range). Depending on what you have available, I like things like Pumice stone in binder (Vallejo has a version of this, so does your local art/crafts store, look for Liquitex or other brands of textured medium), so you can just slap it on the base, wait for it to dry, prime, basecoat, drybrush a lighter color, and you\'re done. A little static grass added in a couple of spots helps too.

This is just the Vallejo pumice stone stuff, with a couple of rocks made out of green stuff.

This is a mixture using Renassance Ink flocking gels - similiar to the stuff you might find in craft stores. Note the different sizes of rocks in them, I used a couple different ones for this effect.

Another one using the flocking gels with a little bit of static grass this time + a piece of dried flower.

This is Hudson and Allen \"snow\". Mix with water, splatter on base, wait to dry and you\'re done. Talk about a 5-10 minute base...
Anyways, this is what I think are good places to start. There\'s a lot more advanced techniques out there, but I think you should get down the basics of shading and highlighting as well as basing before trying more complicated techniques. Hope this helps!
