It's time we had a STEEM coin symbol!

I was working on a presentation slide when I realised that I couldn't find a coin symbol for STEEM. So I started playing around in InkScape. What do you guys think?

I also played around with a few variations of the inverse coin symbol. Vote for the best design!

Which symbol do you like best? Vote below!

After a suggestion from user @pinartemiz (upvote his/her comment below), I am posting a comment with each variation of the coin symbol. If it works, this will function as a voting mechanism to easily see which variation the community likes best.

Source Inkscape files are available for download at bitspace.no

Fix - STEEM coin no longer transparent.
Note: After narrowing down the design, i will update the source file zip with the new designs

Please give your feedback in the comments below!

Update:

Based on feedback from user @summon (upvote below), I've experimented with decreasing the size of the steemit logo within the coin. For now, I include the two most popular colour variations.

I posted the four sizes in new comments. Please comment and/or vote for your preferred size!

After narrowing down to a good size, I will do what @liberosist suggests and adjust the thickness of the border.

I made a couple of variations on the light one as well, in case someone likes it (comment and/or vote)
