Yeah it is good and you look well - I would mix the poses up a bit close selfies, timed selfies like that one and get someone else to take other poses - I think for very early portfolios just pick your best pictures from your own collections - If you get more serious then use photos from modelling jobs you get - Just the usual take care warnings about the modelling world, be sure of all the contacts you make.
Angle it upper, support your weight better, stand straight, tilt your head upward. It will make you look taller and better. Hope I helped.. I modeled for a bit. Shhh don't tell anyone 😉 I wish I could show you a picture..
