Seasons Tree. A pokemon fanpic

An entry for 's latest contest; The theme: 'Change of the Seasons'.
'Summer' is on the upper-left, 'Winter' the upper-right, 'Spring' on the lower-left and 'Autumn' on the lower-right. I arranged it that way mostly cause it was easier to draw that way and because I'm lazy~ XD

As for why there is a Bellsprout in the winter scene or why there is Sentret in a tree... I felt like drawing it that way.

...Actually, It was kind of an accidental, but I ended up mostly using the scenery and flora from the Blue Mts area where I live, so the pic has a real 'Aussie' feel to it. Considering I don't normally go for realistic scenery, I'm actually quite happy with it~
That said, the flora in the 'Summer' section of the pic is either ground flora or non-existant so that part of the pic wasn't so real... And I didn't draw any sort of fern, which grow EVERYWHERE around here... ;>>
The actual tree that is the centerpiece of the pic is known as a 'ghost gum' ([link]) so it's actually over-coloured, believe it or not.

As for the pokemon... Well, try to find them all! There are a few tricky-to-spot ones so invisible cookies to anyone who finds the Cyndaquil, the Suicune and the Butterfree~
