Is it okay to ask people to visit my other gigs in a gig description?

[bits168]

Hello, I started my first gig some time ago. And I got very low impressions. Now I am thinking of splitting my gig into 2 gigs because I feel that my gigs are extremely underpriced for the quality of the work. So I can move my more advanced looking work to the second gig and price it higher. I’ve seen many people suggesting I should have more than one gig if possible.
My question is, is it okay to link any of my gig to other gigs. Like: “If you are looking for even better looking renders, visit my other gig. Here’s the link: xyz”
Will it be against any rules?
And can you also see my gig and confirm whether it is really underpriced.
