I will draw pixelart gui screens, menus and hud assets

Yes, as long as the conditions shown in the "License" section of my TOS are met. if you have any question or want to discuss a custom agreement, contact me.

Pieces of GUI that are smaller than a full screen menu like hot bars, boss bars, dialogue boxes, floating windows etc. good for HUD related works.

The gig packages show a number of included elements, but they are only an illustrative quantity, depending on the particular characteristics of your project, they can be adjusted to offer you a more suitable personalized package, for this reason it is important to contact me before place an order.

Yes, the packages sizes are for the canvas only, you can ask me to scale the assets without losing quality and aspect ratio x2, x3, x4, etc. at no additional cost, Just request it will ordering and tell me what scale you want.

I don't usually offer my source file because it's a set of various custom tools developed for my specific workflow. However, in very specific situations that require it, we can reach an agreement.
