Thanks mate. I consider your advice to remix. I use for the band large room reverberation to put them to the back in soundpicture and for solos no time delay to put them to front. Added to that reverberation "acoustic in mix" to the instruments. I'll check, that they're in balance. I sometimes use for vocals even "voice fattener" that is, a short delay, because I have a weak voice, but with reverberation it leads often too muddy vocals. I have got complains, that I hide my vocals behind the band, so I have raised it boldly up front. Maybe too much in this case?
P.S. This is a great forum, because here I've got polite, but honest and encouraging comments and hints. Thanks for that.
