-- I have a really nice version of this with colors, I'll post it when I can upload it. (Usually I only make the tags Black and White when I cannot match all the colors. )
Hmm... well they're not too bad, but I really think that you should try it with some color. Also some of them look a bit too sharp, try blurring the backgrounds a little bit. Keep workin on them!
Depth will be the next thing I work on. Just have to find some good tutorials teaching ways of adding depth. If anyone knows any and could send me in the right direction, I'd greatly appreciate it.
Some are a bit too bright. There are many ways to work with colors. (photo filters, curve layers, gradient maps, brushing, etc) Instead of giving up and just making it bw, keep working on it since color is an important part of a sig. I think the bw kills the interest in these tags, so give out the colored versions so people can give you advice on how to fix
Everybody has pretty much noted everything. I personally think that your tags are WAY busy though bro. Be careful, cause you can really clutter up a tag and kill the flow quickly by adding too much. Keep it up Good work
