First digital art ever

So I went to a Malaysian equivalent of a Comic Con (#CF2014) and tried out one of the tablets. I may say, this is not bad for the first time. and my hand almost broke off because the tablet was set to a near 90 degrees. I had guidance from the team who maintained the booth because I had no clue how it worked and every one crowded around me and it made it so much more embarrassing.
But now when I looked it up I feel like flipping the table 3_3
It looks so bad
There's nothing I can do now unless making my mom drive 30 miles back to the con and correct it.
I cry
