Why to remove your works?Even though your skills are not helpful for your programmer career,they have no disadvantage for it too!What's more,I think your boss would think you are a talent in game design as you are skilled in a few field of game!

Not a bad thing indeed.

Basically everyone is correct—you should realize that there is no single answer that fits all scenarios.

Your best bet is to put an applicable spin on it. That is, if you can draw, say it helps when communicating with artists or when communicating your own ideas more visually. If you also make music, say it helps you as a programmer to do sound programming.

My job is R&D, which sounds completely unrelated to art, but it means that I also work on or at least use the in-house tools we have developed for Maya, and it just so happened that my experience in Maya is quite helpful for me in this job. So you never really know the worth of those extra little things you can do.

As mentioned, smaller studios will appreciate that more, but even for larger studios it wouldn’t hurt to make a very short mention of it in the “Miscellaneous” section of your résumé, and put a relevant spin on it.

Good luck!

They are worth mentioning if they are good/impressive. In other words do you feel like you could ever make money in selling your art or have enough knowledge to teach someone else good art skills. Looking at your portfolio I would say no. You don't have enough to have someone say "wow they are really dedicated at their interests." You have a very early skilled portfolio, should you push it further then yes. But showing 10 of the same style anime characters really boils down to "1" piece of art in my opinion. Basically the same piece in different ways.
