The poor baby..he does look bad. I second the idea of possibly going septic, and if he gets worse (could it get worse?) it might be more humane to euthanize him.
He also looks like he didn't/can't shed properly, could it be affecting his breathing?
He didn't shed since i got him, and no shedding symptoms that he showed, eyes are perfectly normal his skin a bit crusty now tho.
Hes like he is drying but everything is normal in his cage, i gave him a warm bath too
