Making friends with a girl over Twitter

So, we chatted but now its kind of got left...she is really pretty and I would like to ask her out, never met someone who has as much of the same interests as I do. Its just I don't want to sound awkward and weird, how would I do it on Twitter? Is it even worth it?

Well we got talking. Would actually like to ask her out eventually...but not till I know her better and then perhaps we can move beyond being friends.

So, I have this girl I'm following on Twitter and she is also following me. I actually followed her because she seems to have some of the same interests as me.

I would actually like to make friends with her, but how can I do this without her pushing me away?
I want to make a good impression on her.

Would be grateful for any advice

Start the long and progressive cycles of re-tweets, favouriting, mentioning, etc.

Then when she is reciprocating, which if she likes she will, send her a DM message simply saying "Hi". See where it goes from there..

Have fun..

Reciprocating as in favouriting my tweets, retweeting them, that sort of thing?

Yes..

Do you have a picture of yourself as an avatar?

Does she know what you look like?

I've posted a pic of myself on here. Its my current Twitter pic.
