Nice job mate, I love the colors in there but there are a few basics which need attention....
Depth: There is too much blur, making the depth look forced rather than natural. When using blur for depth only use a tiny amount, for example if you used Gaussian blur then only use a setting of about 0.4px. It is always better to start out small, that way you have the option of increasing later on if need be. But 0.4px is plenty as the rest of the depth will come from the lighting and shading as well as edge darkening.
Lighting: I think you have your light sources placed in the correct areas, however the bottom one should be in front of the render but behind the c4d's. I also think it needs to be more of an off white color, something like a very light yellow. Lastly for the lighting, I feel there is too much light in the tag overall. This disrupts the depth and also the atmosphere, balance is the key when it comes to lighting. In other words you need to balance lighting and shading together, if you do this it will improve the depth, atmosphere and the lighting and shading making it much more realistic.
Flow: What you have around the render is great, its working with the natural look and flow that it gives off. But the c4d's around the edges of the tag disrupts the flow, as does the diamond shape brush or texture you have place in there. In all honesty you would have been better off building on what you had around the render.
Text: Although I don't consider this a basic, I will comment on it since you added it in there. I hate to say it but its a bit plain and boring, when adding text it needs to enhance the look of the tag but not take away from it kinda like "seen but not heard" As it is now it needs more substance, try just using standard fonts like impact for the main word and ariel for any sub wording. But change it up a bit by using standard/bold/black and mix it with the tiny text brush you used. Lastly you want to work with your blending options like stroke and gradient overlay, these will help you blend the text in more.
Atmosphere: This is the last thing I feel you need to work on, the best and easiest way to do that is by using adjustment layers. But before these will help, you need to lay the platform first. This is done by combining everything stated above, also don't fall into the trap of adding a whole bunch of adjustment layers at the one time. I normally use about 5 or 6 to finish everything off but I have usually used about 6 or so before final adjustments. These should be spread out throughout the making of the tag.
I really hope this helps, and I am sorry if I sound harsh. This is not my intention, as looking at the OP you only make tags when you get time. So please just keep enjoying yourself and have fun making them, as that is what its truly about. Only take my tips if you are a little more serious about taking them to the next level. I still think its a good tag, but with a bit more attention to the basics it could easily jump a few levels KIU
