Learning how to do covers, feedback appreciated

[Megatron]

So I am quite the noob at making covers.  In fact, I'm not past the cut and crop stages of cover making.  That said, I am trying to perfect my positioning of images and labels before tackling the harder tasks of cleaning RAWs and whatnot.
Below is my latest attempt to turn a genesis UGC into a red label genesis case sized label.  Any feedback is appreciated.  And yes, this is just a crop from the existing cover, but like I said, I am only in the initial stages of cover development.
My only real gripe is that i wanted to put "Sunsoft" on the spine, but since the text was red it would blend in.  I tried to convert it to yellow with very little success.

Here's another without the seal under the genesis logo

Well, the sunsoft logo would have looked good on the spine. A simple good search produced plenty of blue sunsoft logos that would work.

Thanks for the tip...I found a nice logo that was pretty easy to edit.
Here are some experiments...

Yellow logo is the same yellow as the front, the blue is the same color as the "Batman" logo, and the grey is the same grey as the genesis logo.

ANy suggestions on what looks best?  Or should I ditch it and go with a more pronounced color?
Also, the original cover has the Sunsoft vertical, however with the Genesis logo ont he spine that would become too crowded I think
Also, the logos are different sizes and spaced differently to get some different perspectives

I appreciate your using my template, but the Sega logos and black frames were deliberately included.

For most of my transfers I've kept them.  I definitely wasn't complaining about the logo, just at my lack of skills for placing other logos.  The Sega didn't feel/look right with this particular title.  And someday I may print ALL of my genesis covers with that template to have a nice, uniform library.  But at the moment I am only altering the Genesis games I have that are not red spine, leaving those that are in their retail form.  Thank you for the template, though.  It really is very helpful.

Also, the logos and such can be turned off with the eye icons next to their layers, so you don't have to oversize another logo in covering it.

I did turn it off.  I was playing around with the size of the other labels.  Nothing is really overlapping logos.  Still new at this, so I'm experimenting with a lot.
