The "Siloam" looks like it was forced onto the text of a tutorial piece to me. Personally I would do away with the overlapping shadow, I think one solid shadow would look more appealing. Also I think the shadow would feel less awkward if it was a darker shade of the background rather than a completely different shade of green.
I also would consider how this is going to look in black and white, I have a feeling it's not going to look great.
Why did you choose "
Signs & Design" to be the headliner of this logo. IMO the Siloam should be the largest font if not equal to the rest. It communicates "Generic
sign and design company with little creativity" to me. I don't want to sound harsh, it's just honesty. I feel like I grow in the most in my craft when people are honest, so it's not from a hateful place.
