Zoinks! This is a big \'mini\'. Not impossible but there is alot there so be patient.
First, it looks real good. You are well on your way. What I would say at this point is to paint the back side of the fig\'s black. Sorry to have you go over your nice paintjob. Mabey a DARK wash of black. There needs to be more contrast between front (lit) and back (unlit). The unlit sides of all the parts of the cannon need to be darker.
Now, this is going to sound contradictory to what I have said earlier in the thread. The rings around the barrell, the edges of the gears on the gunmount, the pillow block\'s that the gear connect\'s to - Think of how you figure where to put the \'gleam\' on a gem. Using pure white put the same thing on these parts. The \'gleam on the hoop\'s around the barrell wont be points but an uneven line that goes around the entire hoop.
The grass-dirt under the muzzle flash needs to be alot lighter and have a greener green. Since the muzzle flash leans to the yellow make the grass lime yellow with a touch of white and drybrush that in a circle on the ground that will be VERY (light pastel lime green) light under the flash and diminish at about the axle of the wheels. BLEND this. Dont just have it end sharply.
The muzzle flash itself - Heavily drybrush the MIDDLE 2/3 leving a bit of white in the crevices. Again, blend this but have the transition to white happen quicker.
The front 1/2 of the barrell. Drybrush heavily with the same color/tone you used on the lit side of the wheels. Blend it to darker as it gets back to the gears.
The shadows behind the fig\'s and cannon, go totally black, same with the foliage in the trees. Have the back edge of the diorama be totally black in a semicircle with the front of the cannon being the apex of the curve.
I know this probably seems like alot but doing it over the web is a bit difficult. But DONT LOSE HEART. it\'s comming along just fine.
A few tighter shots of the cannon would help and take 1 mini and shoot it, not changing the elevation, from front, side, back. All this after you have done the above suggestions. Wide shot\'s too.
Till next time!
Seeeeee yaaaaaaa
