You didn't do any work on the "veins" one. You just went to filters > render > lava > ok
Then you added text.
On your latest one, you just took a filter (I can't remember it's name) and took the orange fill tool to the middle, then slapped on a computer and text.
You aren't doing anything yourself on your avatar either. There is a setting on the Ripple, IWarp, and other filters that auto-animates images.
On this one I like how you put a bunch of filters together. I don't like the filters you used though. Just keep working with filters until you find the perfect ones
Good start though. I recommend reading/watching tuts so you don't claim a filter as your work next time
Also, save images as .png, not .jpg. .jpg destroys quality.
