If you intent to develop it then keep it. If you hope to resell for profit then drop it. It has no investment potential.
Generally, avoid two-word ngtld domains and avoid high renewals (i think .global is at $50/yr) unless it's something special.
Also, keep in mind that .global is not a good extension to invest in for two main reasons.
1. .global is just wrong, the word 'global' is better to be in the front('global graphic design' is way better than 'graphic design global')
2. Like in any extension, there are some good .global domains but all are reserved by the registry and are for sale for end-user prices.
Always keep in mind to check the search volume of the full domain you want to buy.
In this case 'Graphic Design Global' has no searches so you should have avoided it.
