If I was to hire you for money or to choose of several artists for a collab, I would like to see all the different styles you are able to draw in decent quality. This way I can judge, if your art style matches the type of game that is planned or the style of the other artists.

The other aspect is, how ‘professional’ you present yourself. There are many ways a portfolio can look and I am sure one can find lots of guides telling you, what is best. But honestly: Any presentation that gets me to what I mentioned first in my replay is good. But if the portfolio is just thrown together without any care (missing or broken links, lots of wording and grammar mistakes) it will leave a bad first impression.

And usually you do not get a 2nd chance for a first impression. So to summarize: Show off, what you have got. Put enough care and love into your portfolio. Do not try to be some kind of artist that you are not (people will realize as soon as you are working together, so: Just be yourself). That’s it.

Do not feel disencouraged by not having hundreds of examples. Your portfolio should present you and your growth.

Good luck!
