cgtt logo

its a nice effort! and it works pretty well.
but i think though that the CGTT could benefit from a bit more weight.

and id use a different font for the type at the bottom. it kinda looks like you just lifted the type in the logo right out of it - which may have been your goal. but in the end, it waters down the mark

Like the combined letters aspect. The rest of it falls into the "satisfactory" category. Not sure you need the CGTT at the bottom - the combined letters are apparent to me.

With a little work, I think you have a winner.

It's interesting but everyone and the author knows there are something wrong.

we can see a combination of three elements to make an two element logo.

the initials are redundant and because this is not a merely business, I think it's better to write the name.

the symbol could work better if rounded. this approach is a lot outdated. you just need to research better fonts to rescue it from 80's.

i see a LOT of logos these days that are primarily an acronym of the company name (i.e. national oilwell varco as NOV) and i consider that, more often than not, just taking the easy way out.

here you have an icon and the acronym AND the name. so it ends up being somewhat redundant. you might work on developing the leaf icon and just have CGTT written at the bottom -

even though i kind of enjoy the type icon you have going ; )

I like it. It's better than many of the pieces submitted here.
I agree with Art D., I'd remove the repeated characters. Consider if you need to include the full name of the organization for a more 'complete' version and where that will go. Consider shortening the vertical stroke of the T characters, they don't need to extend so far down, maybe they can end on the baseline rather than extending below. You may also want to shorten the top of the Ts so that the round shape of the C and G dominate and reinforce the 'fruit' shape their suggesting in relation to the leaves. Thicken the lines, and pay attention to the white space between the lines. Right now, the lighter green and the white are the same thickness. As you make the lines thicker, and narrowing the white space between, you'll get some interesting dynamics with that white space.
You might also consider rounding the ends of the lines. It'll be much softer and organic feeling.
Try moving the leaf element down, closer to the characters. Right now it's far enough apart that they don't feel integrated. You may also want to rotate the leaf a little bit clockwise, it'll fit in closer to the characters if it's rotated a bit. You might also 'split' the leaf element with color, it's really two leaves anyway. Make the 'back' one the darker green shade, corresponding to the stacking order of the characters.

Really nice, w. equal weight (G could perch on the lower T) and lose one leaf; you don't need the spelling underneath.. it's cool!
