Thanks all! Looking back at this project I definately would have done things a touch differently. I'm happy with how the figure is painted, however the base I think would have gotten a complete redo (which I may still do one day)
I was at a place where I wanted to try to combine 2d and 3d techniques where I think it would have done better to actually use 3d bricks to build the base and wall and make it a bit more...realistic.
I also agree about the shadows, and it was a result of my choice above, when I diffused the shadows too much which I had done at first, with the freehand brickwork, it made it look kind of too blurry, it didn't look right either. I think with real bricks I will have more freedom with the shadows as well.
hmmmm, I am getting inspired now to redo the base, I'll have to put it on the to-do list
Thanks for the feedback all!
