Not bad - I'll explain why I gave only 3.5 stars.
The idea is good - I feel like I would like to see an interesting illustration in addition to the text. I really like the handwritten font (I don't know if you did it yourself or used one but it fits well) but I think it should be organized more "eyecatchingly" (Is it a word?) and have some more depth - maybe adding a bit of shadow to the ctrl button, or making the letters bold and "stronger".
In conclusion - It's good, could have some more ambition - Make your creativity burst more and show off more, and have fun!
