Before I started Graphics designing with my smartphone. I asked a graphics designer if I could make 3d logos with smart phone. His reply was no. He said it can only be possible with a laptop. But that is not true, the world has evolved so much that you can do alot of things with your smart phone including 3d logo designing from scratch, Flyer designs and many others. I now have a laptop but truth be told I prefer designing with my phone most times. And another thing alot of Graphics designers will hide from you is that there is money in Graphics designing. You can work on different freelancing sites and also get work around you.
I offer free Smartphone Graphics design class every month. If you want to be part of it you can just send me a WhatsApp message 08131340722.
