[GRASS-user] landsat and srtm blend

[alrc]

Hello, 
I try to make simple (in theory) shaded relief based on SRTM data and blend
it with Landsat7 RGB composite. 
I have converted SRTM WRS2 (p187r025) tile from LatLong to UTM z34 to match
my Landsat data. The thing is that the landsat image is somewhat
rotated/skewed, which I guess is specific to ETM imagery rather than to UTM
projection. When I try to combine rasters using r.blend I get an misaligned
image. 

Here is the shaded relief I want to use:

and r.info:

Landsat raster:

and info:

r.blend result (d.rgb used to display color channels):

What can I do to make terrain on landsat image actually face north as is on
the srtm relief? 
I spend much too many hours on this issue, any help will be appreciated. 

Tia,
