At Skyweb Studios we produce artwork for a lot of bands and we can not be held responsible for our clients and their music. We only work with the client on design work.
We do not use assets that do not belong to us, everything in the design process is created by Skyweb Studios. From time to time we may use a few assets to help us produce art work but only when those assets are free to use and have the right license. For example, we may use free brushes in our designs from time to time when ever it is conveniant.
