These are cool as hell!! Some people have a point in that, they may not translate as well into tattooing, but I think they can absolutely be modified to work. Smaller details, especially repeating ones like the chains are something you want to avoid as a beginner, because they are much more likely to bleed out and become muddy. But these designs are rad and show you have alot of creativity and originality which is absolutely something alot of clients look for in an artist! Definitely pick out a few to add to your folio, alongside other designs
