:< Its prettyfull deal with it

no you. :<

:< No, me.

Who, me? Yes you! Couldn't be! Then who? :<

It's like you're one of the pokemon, peeping out of a tree trunk at them!

He is a creeper peeper :<

Now that you mention it, it does look like the interior of a tree trunk. XD That wasn't the intention but it so works.

Yup. ^^

Aww, I heart these Pokemon, too. :3

Since you've asked for critique, I'll try to give some.
Inking isn't really all that hard. To make the lines smooth, just erase the bits that aren't. :B
I like how you have thicker lines up close, and thinner further away. But then the furthest tree trunk has thick lines again...
You seem to have forgotten to colour the ground seen between Whimsicott and the tree. : O
I really like how soft this picture is. :3 Just keep practicing. <3

I wasn't really sure how dark to make the grass without losing the brightness of the picture, but yeah I could probably do with a LOT more variation in shading/highlights. x3 I was mostly messing around with the brushes to try to get used to SAI, and I found a better method like an hour into doing this than I had already been using, so some 'techniques' might not match all that well throughout the whole picture. @_@
As for the line thickness on the other trees, I was trying to give more of an illusion of depth; as they were going up, thicker lines to indicate being closer to the 'viewer' and whatnot, but I think I did it too literally in this case.
The grass and overall background was the last thing I was working on so I rushed it a bit too much. ^^;
