Hi, well done on making your second signature, it's definitely an improvement from the last one!
Rather than do my massive paragraphs like last time, I'll give you a few pointers for further improvement.
- Move the text closer to the signature: It just makes it look a bit better. If you want to add some cool effects to the text then you can mess around with it by right clicking the text layer and pressing Blending Options. Text is looking better this time by the way, good job.
- There's too much space above the renders head, you can either crop out the top part of the signature or just make the canvas a bit shorter next time
- The C4D flows nicely around the render, but I feel like you can do a bit more to make it blend. Try playing about with the smudge settings a bit more, there are tutorials out there which can help you with that. I also feel that you can make the colours blend a bit more, perhaps darken some parts around the signature. Good job on making the render the focal point.
- Last of all, don't be afraid to experiment. Play around with textures, C4D's, filters, colour effects etc. and mess around with the layer types and opacity. See what fits! You can add a border too by creating a new layer, selecting the whole canvas with the square selection tool and going to edit>stroke, then play around with the settings.
Great job, not many people can make signatures as neat as that when they first start.
By the way, in case you're wondering what my first signature looked like, you can find it in one of the topics in this section called "What was your first ever signature?" :p
