I would make all the labels the same color as the title (yellowish gold) so it would stand out more and they would have matching colors.
Your title has a box around it and it is pretty easy to see that it was cut and pasted on the form. There is a fine visible line that goes around the title where the background and background of the form doesn
t match up. It would be better to just make the title on a transparent form and then put it on the form.
Don't ever use .jpg for a preview. You can see the image's quality is deteriorated. I would recommend using .png or .gif and save with highest quality settings.
You might want to add labels for what the two textboxes do. The first is the process and the second one is the DLL's but it can be confusing to someone new with injectors.
Also, if you do not already have, after it has been injected, add an option:
[] Close after injection?
So people won't have to close it themselves.
