I use instagram, yes! It uses a different name though because some low rate hip hopper from Hamburg or something was faster taking my name <.< :
I also have a facebook page, which should grow some more but I am against paying facebook for advertisement
I also have devianArt though dA really sort of became a garbage place imo ... too much weird fetish porn around (yes, I could put on the mature filter, but then I'd miss other good art as well. I can't have one without the other it seems):
Have a swell day!
