Thanks, and it says were I live in my profile description. And yes I could wip up a few tiles for you.

looking better man you have imporved alot can I ask you were you live? I may need some tile made for a mobile game I will be working on and may need some help, but I can't promise anything I say again, I can't promise anything.  cau

Once again, nice work.

there fixed, now has a more atmospherec look to the backdrop

it looks better now, thanks

Pretty neat! I really like the colors on the pipe, and the text has a neat look too. I do think your style is a little too much for Mario's general simple style, but it works.

However, I do see some technical errors. For example, your background gets darker as it goes into the sky, when really it's the opposite. When you look at things in the sky, they actually loose contrast and blend into the sky. so really, the back drops should get lighter as they go back, and it might look neater if you gave them some tints of blue. You do have the right idea of simplifying the objects' details and textures though as they go back further. :)

Another major issue is defining what's where. Like, the bushes that are on the ground layer, those blend in too much. (Although, making the large bushes or tree tops dark like I suggest would define them better.) You also make the pallets to similar on each layer. (Or maybe you don't change them... I didn't check. >.>)

In any case, tinting the background colors just a little can make a difference there in defining where things are. "These bushes a little blue, so they're back further." Or, "These bushes are more vibrent, so they're up closer."

I also didn't really see the Goompa or POW block at first either. It may be because all the details make the background a little busy, but I think the colors also play a part. (The POW block almost has all the same colors as the mountain's... or at least color scheme.)

Another thing that kinda sticks out is how the clouds seem a bit random. They're small and scattered far apart, and that doesn't make a lot of sence. Typically, you've got a few clouds if they're small, other wise they'd be big right? :P

But what I said makes the screen seem pretty negative. It's not, it's got some nice stuff going for it, like your pallets for the mountains and bushes, and tile design, but still needs some work.

I really like all of your mockups. Might wanna try something other then mario sometime, eh?
Good job on everything.
