Their concept of designing in 3D brings them closer to their target audience than traditional ways (printing/photography).
I like how they combine creativity with professionalism when working together creating artworks or designs from scratch; we've built several websites from concepts developed by these guys! Sometimes it can take time but always worth waiting as you're getting great results at last minute rates ;-) They also have very nice UX design team who do UI & icons work flawlessly - just what every developer needs! Nothing really specific right now except maybe some minor bugs which are being fixed quickly. We use silvos' web development services mainly because our previous agency went bankrupt so had no choice other then hiring external developers.
