"Digital Crafting Agency" Is only slightly better in conveying what it is your company does over "Digital Agency".
"Digital Agency" could mean any sort of company that works with computers (Not even necessarily web-based, because every electronic display device this day with few exceptions is a "digital device").
Adding the word "Crafting" only further expands upon this description by saying you create some sort of product that is digital, which is quite a broad range of objects, even if we assume it is only a web-based product (and if we do assume that, then it encompasses every single web product that exists).
You would be better off advertizing your company by stating clearly the exact product that you offer. If you offer a broad range of web-based services, you could call your company a "Web Development" company. Or if you produce digital interactive devices such as mobile phones, you could refer to the precise object that you produce.
Depending on what your company actually makes, you have a plethora of different options for how to advertize your services. But neither "Digital Agency" nor "Digital Crafting Agency" offers much in the way of explaining what it is your company does.
