I think you should shorten the ‘development group’ name to something more catchy, such as ‘creation group/team’. I personally don’t like the shortening of ‘development/developer’ to ‘dev’, but you can of course use that if you want.
I think the neon blue at the top of the group logo should use less green, it will match better with the below colours.
I also think a softer, less sharp-edged gradient would look nicer, unless you are specifically going for this style.
