I tried to shift the lightsource to a top-down angle for your character. The shins look way long. Where are his knees?

Damnit that's a great edit! You spotted my issues.. well.. spot on. Thank you ErekT!  

I've tried to correct the sprite according to your edit. Also had a go on the knee issues.

Healthbar and countdown added(WIP):

Thank you pistachio, very good crits there.

I tend to mess up lightsource in almost everything I do. Tried correcting the lightsource, not sure if I got it right.
Also tweaked/brightened up the colors on the sprite and added some detailing on the environment.

The threetop/leafs are beginning to annoy me.. they look.. busy and flat..lol

update:

Added some more texture/details on the trees.
Planning to add a stonebridge going through the opening of the forest.

Nice!

Could you make a tilemap in the style of the second to last mock-up?

Ofcourse, they're actually both tilemaps made in Tiled.

Ok, finally had some time to work on this piece. Atleast rework the tree.



This still needs quite a bit of polishing.
C&C!
