I like it. Text sucks...but thatsa given for like 90% of GR and in your sig...you spelled critic wrong >.< Just thought you'd wanna know.
Text could use some work IMO. Also, the colours don't seem to blend very well, the render and background don't go all that well together and the effects could have been done so they were a bit less visible IMO. Try to get some depth as well. Just my thoughts.
