It is all valuable practice and progress, so keep that up!
I do think posting the external link to your work will make people less likely to check it out, with the extra steps they have to go through to see your work. If you feel like you are posting too much, then post the pieces that you are proudest of. Of course, you are free to continuing posting the link, I just thought I'd mention that I almost didn't click through to see your work. Cheers and keep on making marks!
