Max,
First your overview of talents and lack of conversation is really missing power, also your TITLE area needs something like Video Editing | Premire | After Effects instead of just Video Editing. Here is my profile to show you how I added several Titles and created a nice long, Get to Know Me overview.
As for proposals, they need to have great English, be compelling to the point the client has to hire you, and really spark interest with the client. I have won jobs by just writing two lines that told them their ASAP can be done Now and that I wasn't going to tell them how great I am, read my client reviews. I have also won jobs by using simple humor, most of the time I write to the client what I would do to their "logo project" and how I invision a new approach, I aslo tell them that they will get this and that formatted graphics for all their collateral needs.
I started in April and have about made $10,000 and am now Top Rated.
So in the end, make your profile shine, write great proposals and keep looking for jobs, one of them or even 5 will come calling and somethimes at the same time, making you a very busy person.
Go check out my profile and see if it gives you any ideas.
Good Luck and Much Success.
