I like the direction you were going with the pen. I would work on the pen a bit more though. Perhaps the cap of the pen could double as the dot on the i, serving 2 purposes, making it read better as an "i" and as a pen.
Perhaps try another option with tighter kerning. and maybe a bit more unique type style. I think your instinct to go with a case sensitive sans-serif font is a good one, that screams "office supply" for some reason, I just think it needs more character if it's going to be a logo type. There are a few nice ones to play around with here:

I actually don't mind the pen crossing the "t"... Here again, good direction, just a bit more work on the execution. Perhaps a better font there might help too. Think legibility.
I agree with flame, not bad at all for someone who is new to design. A lot of new designers try to throw everything they have at a design and it comes out looking like a mess. Your design, although it needs some fine tuning in my opinion, is easy to take in, now you just need to work on making it stand out more as an individual brand.
