I bet a lot of people find this place because of boredom.
Welcome to the Sig Shoppe.
I've been wanting to do another Pokemon sig for the longest time, so kudos for the idea. I like your colors, an analogous scheme works well in a lot of instances, and I think it's a relatively easy scheme to grasp.
Something to be careful with when you're using text is having two different focals. They're in opposite corners and different fonts as well. This draws our attention in 2 separate directions which can be confusing/unappealing. I would say, for now, choose one area you want to have the text in and probably make it smaller so Haunter's the main focus. I'm also thinking the color of the text should stand out more, maybe something that will contrast magenta/violet. Simple fonts are sometimes best. The :
093: is really blocky and slanted, and the dripping blood look of "Haunter" is kind of over the top. I recommend something a little plainer like Futura/Helvetica to start off with.
I'm not a fan of borders, but that could just be me.
To me it's just taking up space that would be better used filled with graphic effects. Then again I have seen nicely done borders, so I dunno. I don't really like how Haunter's cut off at the top and bottom, but I think you can make it work. It's a good start, it just needs... more. More stuff to emphasize Haunter as the focal. This can be done a number of ways, draining the color from the areas farthest from Haunter, blurring certain areas to create depth, etc. I want to see more elaborate things done with the background and foreground.
I would highly recommend browsing the sigs in this thread for inspiration on making high level sigs. Just study some of them and try to figure out which ones you like, and what makes them good.
