Oooh. Wow.
I'm seeing some very lovely works here, Marina. ^^
You have good contrasting skills with renders and the bg. You nailed some of the texts, too!
The only real problem is those sharp renders, but that can be easily fixed. I pretty much like all your bg on the sigs, they are really something.You have some sort of 'Soft' type of sigs going on here. I like, I like!
Keep it up, and I hope you get rid of the sharpness thing going on. xD
Everyone loves cookies. Yeahh~?
