@ksfabian i used a psuedonyme since i started and i don't regret it.
I think its no problem in the end when its establsihed early.
Just look around who works under a psuedonym.
I wonder if its unprofessional when you work in the industry though, but as a cartoonist, it would'nt seem probplematic for me.
In the end i dont make a secret of my real name though, it's all over my webpage and in my impressum.
