it looks fine,the overlapping is not a problem,I put mine on in pieces sometimes,as long as there is no pockets of fluid under it,I leave it on for 3 or 4 days after the tattoo,it will already be at the peeling stage,I love that stuff.the warm feeling is also normal.it looks fine.
Saniderm(the one I use) says this " For large areas, pieces of Saniderm may be overlapped ".
