Congrats on the little boa boy! He's a little cutie, and looks pretty happy in his new home. Don't even let his little imperfections bother you, because I can guarantee that they won't bother or affect him one bit. In fact, they just add characterOh, and post more pics when you can so we can see him
Only thing I'll ask is this....is the kink in his tail before or after the vent? If it's after, then there will be no issues at all.
Edit: From looking at the pic again, it looks like the kink is after the vent. ALL GOOD!
