I'm dead sure the author has plagiarized a few items from HoMM3. I doubt UBI soft will sue small projects, but DMCA takedowns are not a joke either. Use with care. I'm also ashamed my Russian compatriots cant come with something original and steal designs :(
Viewing post in Heroic Asset Series: Icon Pack comments
No need to be so rude. If it seems to you that with some icons there may be problems with DMCA. Just write it in a friendlier way. This game asset series was completely inspired by HoMM games (all games in the series, not just HoMM3).
Did I have the original idea of coagulating a whole series of games? No, I just drew my Overworld tileset.
As a result:
1) I'll redraw some old icons and draw some new ones.
2) Don't be so rude. And If you're dead sure of plagiarism just warn the author about it. (it can just be a homage, think about it).
3) I'm also ashamed my Russian compatriots cant be a little friendlier.
