I see you also have this available as a print, and while I don't need a print - it would look awesome as the title screen on a promo concept video I'm doing for the non-profit group I'm helping @ #Descent-To-UDK!
So, if you'd like a bit more exposure - I'll be posting the video on youtube so I can link it to the group for the SOL Contingency project. So it would just need an 'image courtesy of' added to the image with your SIG so people know who made it!
If you decide it's okay to use yes, a sig, initials, or your artistic iconic symbol? However you would normally be identified with your work, although it should be readable @ 720x480 since that's the resolution I'll be rendering it with for my youtube account.
Or I could simply add the 'Image courtesy of: Ihsandi Dwinanto' myself, or just 'Andi' if you prefer? Or even 'andiihsandi.deviantart.com' as many artists use.
I'm simply trying to satisfy DA's content permission requirements, since the video will be posted here too! And you do have it available for prints, so I'm just making sure it wouldn't be requested for removal because of your image as the title screen of the video.
