Hi Steve,
Great job on the DPM. It's probably one of the hardest camo patterns to paint because its so well known. It's also quite complex to replicate and has so many tonal variations.
One of the observations I made in my SBS was that some of the shapes in the camouflage pattern actually look like brush strokes, and the colours aren't clearly defined and separate blobs but overlap in a layered sequence. I'd like to see a few more brush strokes effects used, especially with the green colour, to enhance the overlap of green on brown, and green on sandy yellow.
I'd also like to see you increase the level of contrast between the highlight and shadow colours within the DPM scheme itself. At present the brown and green colours looks to be a uniform tone of brown and green all over the figure. In reality these colours will vary according to the light and will also will be affected by weathering and other environmental effects. Don't be afraid to push the highlights a bit more, especially around the top of the shoulders, the top of the chest pockets and the collar.
I would follow Gells advice and apply a green wash over the DPM once you've finished, however my suggestion would be to apply a green wash over the jacket only, and apply a sandy brown wash over the trousers. Not only will the washes help to make the colours more drab, but it will also help to create that variation between the blouse and the trousers that comes from wearing different bits of kit at different times and in different conditions. I would also hit the knees, elbows and bum areas with some weathering pigment to match the groundwork you intend to place the figure on. The trousers should always look more distressed and weathered than the jacket because the trousers are worn constantly and come into contract with the ground more often.
My advice Steve is to be bold and keep working on the DPM, not matter how far out of your comfort zone you think you are. You may think that you've finished but there's always a bit more you can do. When you look back on the results later, you'll be glad you took the time and made the extra effort.
Keep up the good work mate.
