Thanks! Yes I do agree about the grass. Grounds were never my strong point. But thank-you for the advice, I'll definitely have to mess around with this more.
The hole is a bit distracting... I feel like it shouldn't be so dark in there, given how large the opening is. Increasing the contrast of the bark texture could give a greater dense of depth.
I quite like the palette!
I noticed the style of the leaves and it reminded me of the tutorial but it's good to see you went off on your own and changed a lot of it, trunk looks really good.
The only problem I have (and a small one at that) with it, is that the way you've done the contact with the ground, it looks like it's detatched a little. Maybe try breaking up the line or lightning it a bit?
Yes, I see what you mean by the hole being distracting. I'll have to try fixing that. Thanks!
