Hey, seems like you've put some serious thought into your ideas. There is something that captures me with the second image. I don't mind how "deep" into the internal struggle that it is. I'd love to see you do some more on that one. The only thing that looks out of place a little is his expression. I know you were going for "there are more inner struggles to come", however, it is still to maddening to lose everybattle. But, alas, it is sometimes too hard to work on something that you are not inspired by.
The last image is very nice and bright. I really love the greens that you've used. The idea is great too. I keep picturing a small child leaning on his elbows, dreamily watching his dad complete something well wished for. It is hard to tell what you will change at this stage, but the treehouse ladder's shadow seems a bit off? Or maybe its because you havn't added the trees shadows in yet?
Best of luck. Love your painting style. I'll keep my eye on your stuff.
