Very nice
I like the idea of this and the glow is nice on this one I think this one could use more of that glow effect maybe if you ran this through Photoshop and had more of a glow effect especially around the edges and that would give off a nice touch and feel about it but anyways nice idea here nice element and nice effect so keep doing what you do and bring more ideas to the portal such as this fine piece you have here
~~THINGS TO IMPROVE ON~~
Some more glow effect for sure
