I like the second banner more. A bit of an improvement compared to the monotone nature of your other tags. But I think the lighting needs work. Spam more dodge and burn tool, man! XD; As for the first tag, the render has blended nicely and I like that. But the lighting's messed up here as well because there isn't really one single light source. You probably went a little overboard with the effects as well, imo. Keep it down a bit because the render is being overwhelmed by the sheer amount of effects in there, as I see it.
I could totally do that if I remembered where I got them from. :c But unfortunately, I've gathered stuff from various sites. Quite a lot from deviantart. So I don't really have any link, per se. But I definitely plan to upload my resources sometime soon. When I do, I'll link you.
I'm a member of quite a few graphic forums. If I want criticism, I just post in those. Not really interested in joining another atm, sorry. Maybe sometime in future.
People have ways of getting photoshop if they need it. Most of the ones who use it did pirate it. lol And I really don't know why there's such a less % of user-base interested in graphics. Maybe they're just intimidated. :[
Oh, and post message on my profile. Not your own. XD;
Very few people, man. The ones who made it active before have all but left the site. Only I, you and the super moderator Abnegation still love graphics. Others are a little busy these days and don't really post a lot. :[
