OK.  The title/ending stuff is looking better. They still need work, but I'm taking a little break from them. I want to work on the in-game graphics a little.  Right now I feel like they're kind of bland. Any suggestions on color/readability?  Anything stand out as looking weird? I'm already aware that large patches of trees look kind of awful.

Whoops. I edited as you were posting...
I changed the shepherd to look more like the flat-shaded dog portrait.  I agree the dog in the truck still needs work.  I always look at references, but it usually takes me a few tries to get anatomy right. 

I think part of the problem is I wanted to show his tail wagging, and that requires a really awkward pose.

edit:

Better?

edit: also worked on the title screen some more:

Wow, thanks for the edits.  They're giving me some good ideas.

I think part of my problem is I never really settled on a graphical style for this game. There's cartoony stuff, some more realistic renderings, and some colorful, sloppy sketches.  For example, this is the shepherd who pops up every level in a textbox:
 

I thought that rough sketch style would be a nice break from the more sterile looking tile art in the levels.  Aside from the fact that the face is hard to read, I like it.  I think I want to keep it in this style, but it's probably the most dramatically different from any other graphics in the game.  Now I'm wondering if I should redo the cards and title screen in a style closer to this, or if I should make the shepherd's portrait more refined on the pixel level...

This is something that's been happening when I use Graphics Gale, and it's really annoying.  When I copy and paste something I've selected with the lasso tool, the area outside the selection, instead of staying transparent, turns into a solid color...  It seems to happen regardless of the color depth I use, the transparent color I've selected, or the layer I'm working on. It makes the lasso completely useless, and the same thing happens when I use the circular selection, or shift-click for multiple rectangles...

Is this a bug, or am I doing something wrong?

I started working on it a little before you guys commented, and kind of moved in the opposite direction of what Facet's suggesting-- smaller and more centralized 

I feel like a lot of negative space fits with the graphical motif in the game... Simple, minimalist menus and the same green background everywhere. 

It looks like it's all leaning to the left to me.  Try turning it upside down and getting things positioned where you like it.

Yeah, I see what you mean.  I'll try to balance it a little better.

I'd put the wolf (lawful evil) next to the regular, defenceless sheep and the ram (chaotic neutral) apart .   

Good idea.
